JD 3010: Oil dripping from everywhere

[varmint]

If this info helps the OP, I will be very impressed with TbN and what it can do. I am already, but specialized repair knowledge for the asking is amazing. I'll be eagerly watching.

I agree with the prior poster check the fuel transfer pump first. They are easy to change relatively cheap and it would be my first culprit to check. About $40 at NAPA last time I bought one in 2010.

So based on the OP the loud noise could be the pump was frozen and the cam forcing the pump made the noise?
Hope that is the culprit.

That would be a nice scenario.
What really concerns me is what can happen to an engine being lubricated by diesel fuel in the crankcase.
Until my supposition is confirmed, the oil changed and the tractor started, it is too so to be happy.

Nice write up on the pump, Dave.:thumbsup:
I'm thinking that since the oil was so contaminated with fuel it started pushing out the vent pipe like the OP described. Since the engine was now running on basically fuel and not oil, the loud bang he heard was something internally that gave out. It may be too late to recover,
But I do agree that the pump (mechanical) may have been the cause.

I agree with skyhook and that was a nice write up by Dave. Hope the OP did not loose the engine. The good thing is that a 3010 is a fairly easy rebuild if necessary, I would do it myself if the rest of the tractor is in good shape. These older tractors seem to hold their value well enough that a restoration is plausible.

I also agree Dave did a nice job on outlining repair on lift pump BUT some newer replacement pumps aren't rebuildable. I'll add that if the lift pump isn't the fuel leak problem then I'd suggest to look for faulty inj pump drive shaft seals

Dave, your post was incredibly helpful. Being a rookie mechanic I need that kind of instruction. Unfortunately, when I disconnected the lift pump from the engine and worked the little lever I did not see any fuel seeping out the back of the pump. Next step is to check the injectors?

 

[ovrszd]

Injector pump I'm afraid.

MinnesotaGuy.
Out of an abundance of caution, I would still replace the lift pump as it is the cheapest fix you can try.
With the engine running the lift pump lever will be moving quickly up and down and perhaps you are not simulating that condition with your test.
Certainly its not the injectors for the quantity of fuel you describe being in the crankcase.
The injection pump is likely the next culprit and they can be serviced at most diesel repair shops who only work on injection pumps and injectors.
However, the pump likely needs to be timed when reinstalled and unless you have a shop manual or have done it before you will not be successful and can cause damage.
The timing of an injection pump is the same essential task as setting the ignition timing in a gas engine. You are making certain that combustion will occur at the correct point in the movement of the piston.
Change the oil, replace the lift pump and closely monitor the crankcase oil level to see if it increases at all.
If it does then find a mobile diesel mechanic who makes house calls and arrange for him to remove the pump, have it repaired and re-install it.
If you cannot find a mobile mechanic familiar with the JD engine, you could consider buying an on line shop manual so you would know if any special tool are required and how to properly time the injection pump.
Amazon has a printed version which is likely a photocopy of an original but at $64 likely a good buy for someone like you
